Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to flame lamps. Background Technology

[0002] Flame lights are lighting fixtures that simulate flame effects by having multiple LED beads light up and off in sequence. Existing flame lights can only show up-down flashing and lack left-right swaying effects, resulting in limited flame simulation and a monotonous visual presentation. Utility Model Content

[0003] In view of this, the present invention provides a flame lamp and a flame lamp to solve the problems of existing flame lamps and flame lamps.

[0004] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes:

[0005] Flame lamps, including:

[0006] A strip-shaped substrate having a length direction and a width direction;

[0007] Multiple light-emitting units are arranged continuously along the length direction of the strip substrate and staggered from each other in the width direction of the strip substrate, and the multiple light-emitting units form a light-emitting path;

[0008] A control module is provided for controlling the lighting or extinguishing of the plurality of light-emitting units.

[0009] In some embodiments, the strip substrate is arranged in a tortuous shape along its length, such that the arrangement path of the plurality of light-emitting units is tortuous.

[0010] In some embodiments, the strip substrate has an S-shaped tortuous shape, such that the arrangement path of the plurality of light-emitting units is S-shaped.

[0011] In some embodiments, the strip substrate has a Z-shaped tortuous shape, such that the arrangement path of the plurality of light-emitting units is Z-shaped.

[0012] In some embodiments, the strip substrate has a Y-shaped tortuous shape, such that the arrangement path of the plurality of light-emitting units is Y-shaped.

[0013] In some embodiments, multiple strip substrates are provided, and the multiple strip substrates are connected end to end along their length direction.

[0014] In some embodiments, the arrangement path of the plurality of light-emitting units is one of S-shape, Z-shape, and Y-shape.

[0015] In some embodiments, it also includes:

[0016] Multiple electrical connection lines are arranged on the strip-shaped substrate;

[0017] At least two light-emitting units constitute a light-emitting group, wherein one end of each of the two light-emitting units in the light-emitting group is electrically connected to the same electrical connection line, and the other end of each of the two light-emitting units is electrically connected to another electrical connection line, and the conduction directions of the two light-emitting units are opposite.

[0018] The control module is electrically connected to multiple electrical connection lines. By controlling the level states of different electrical connection lines, the control module can make multiple groups of light-emitting groups light up or turn off.

[0019] In some embodiments, the number of electrical connection lines is M, and the number of light-emitting units is N. The M electrical connection lines and the N light-emitting units satisfy the following equation: N = M × (M-1).

[0020] In some embodiments, when the control module controls any light-emitting group to light up, it applies a voltage level to only the two electrical connection lines connected to that light-emitting group, while keeping the other electrical connection lines in a non-conductive state, so that multiple light-emitting groups light up sequentially from the first group to the Pth group, or sequentially from the Pth group to the first group.

[0021] In some embodiments, the control module includes a switch and a gravity sensor, the gravity sensor being linked to the switch, the gravity sensor being used to change the connection circuit of the switch when the flame lamp is placed upright or upside down, thereby changing the lighting sequence of the multiple groups of light-emitting groups.

[0025] By employing the aforementioned flame lamp, the staggered arrangement of the strip-shaped substrate and its multiple light-emitting units along the width direction, combined with the point-to-point lighting sequence of the control module, allows the light-emitting path to exhibit zigzag shapes such as S-shapes, Z-shapes, or Y-shapes. This adds a dynamic left-right swaying effect to the traditional up-and-down jumping flame effect, significantly enhancing the realism and visual appeal of the flame simulation and meeting the market's demand for flame lamps with higher simulation fidelity.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] See appendix Figure 1 -Appendix Figure 2 Embodiment 1 of this utility model provides a flame lamp control circuit, which includes multiple electrical connection lines S, multiple light-emitting units, and a control module 40. The number of multiple electrical connection lines S is M, where M is greater than or equal to 3; the number of multiple light-emitting units is N, where N is greater than M; at least two light-emitting units constitute a light-emitting group 100, wherein one end of each of the two light-emitting units in the light-emitting group 100 is electrically connected to the same electrical connection line S, and the other end of each of the two light-emitting units is electrically connected to another electrical connection line S, and the polarity directions of the two light-emitting units are opposite; the control module 40 is electrically connected to the M electrical connection lines S, and the control module 40 controls the level state of the two electrical connection lines S connected to the same light-emitting group 100 so that different light-emitting units in the light-emitting group 100 are lit alternately.

[0047] Specifically, multiple electrical connection lines S are laid on the circuit board, and multiple light-emitting units can be arranged sequentially on the circuit board. The circuit board can be designed as a straight strip to make the flame effect jump up and down. The circuit board can also be designed as an S-shaped, Y-shaped, or Z-shaped structure to make the flame effect swing left and right. Multiple light-emitting units are arranged on circuit boards of different shapes to achieve different flame appearances and light-emitting effects. The light-emitting unit includes at least one light-emitting diode. This embodiment uses two light-emitting diodes for illustration. In other embodiments, the light-emitting unit can also use one or more light-emitting diodes. One end of the light-emitting unit is the positive terminal of the light-emitting diode, and the other end of the light-emitting unit is the negative terminal of the light-emitting diode, such as... Figure 2 As shown, in the same light-emitting group 100, the positive terminal of one light-emitting unit U1 is connected to an electrical connection line S1, and its negative terminal is connected to another electrical connection line S2. The negative terminal of another light-emitting unit U2 is connected to an electrical connection line S1, and its positive terminal is connected to another electrical connection line S2.

[0048] The alternating illumination of two light-emitting units within the same light-emitting group 100 is based on the voltage level combination relationship of two electrical connection lines S. When the two electrical connection lines S are at different voltage levels, one light-emitting unit in the light-emitting group 100 is lit, and the other light-emitting unit is off, such as... Figure 2Light-emitting units U1 and U2 are connected to electrical connection lines S1 and S2, respectively. The positive terminal of light-emitting unit U1 is connected to electrical connection line S1, and the negative terminal is connected to electrical connection line S2; the positive terminal of light-emitting unit U2 is connected to electrical connection line S2, and the negative terminal is connected to electrical connection line S1. When electrical connection line S1 is at a high level and electrical connection line S2 is at a low level, light-emitting unit U1 lights up, while light-emitting unit U2, due to the opposite diode direction, is in a cutoff state and does not conduct, i.e., light-emitting unit U2 is off. Similarly, when electrical connection line S1 is at a low level and electrical connection line S2 is at a high level, light-emitting unit U2 lights up, and light-emitting unit U1 is off. The light-emitting unit U1 can be turned off by changing the electrical connection line S1. The combination of the electrical connection lines S1 and S2 (i.e., the inversion of their levels) allows the light-emitting units U1 and U2 to be lit alternately. Furthermore, when the control module 40 controls any light-emitting group 100 (composed of light-emitting units U1 and U2) to be lit, it only applies a voltage level to the two electrical connection lines S connected to that light-emitting group 100, while the remaining electrical connection lines S remain non-conductive. This avoids circuit interference between different light-emitting groups 100. Specifically, the remaining electrical connection lines S can be made highly resistant or disconnected, so that the light-emitting units connected to the remaining electrical connection lines S are not energized and will not be lit. Therefore, by changing the voltage combination of the two electrical connection lines S connected to the same light-emitting group 100, the control module 40 achieves the alternating lighting of the two light-emitting units within the light-emitting group 100, thus allowing for control over the fine granularity of the light spot within the same light-emitting group 100. In other embodiments, four or more light-emitting units may be selected to form a group of light-emitting units 100, in which case every two light-emitting units may be lit or turned off simultaneously.

[0049] Combining the alternating lighting of two light-emitting units within a single light-emitting group 100, on a specific circuit board, multiple light-emitting units are arranged sequentially from one end of the circuit board to the other, with adjacent light-emitting units forming a group 100. Multiple light-emitting groups 100 are arranged on the circuit board from one end to the other. The control module 40 controls the light-emitting groups 100 at one end according to a timing sequence, causing the two light-emitting units within that group 100 to light up sequentially, then the two light-emitting units in the next group to light up sequentially, and so on, lighting up subsequent groups 100 in the same way. This results in the entire circuit board being illuminated sequentially from one end to the other, transforming the simulated flame dynamics from a rough, jumpy effect to a delicate, point-by-point progression. Furthermore, since the number of electrical connection lines S used in this control circuit is less than the number of light-emitting units, within a single circuit board, given a fixed number of electrical connection lines S, the control circuit of this embodiment allows for the placement of more light-emitting units on the circuit board, enabling these units to light up sequentially, thus making the simulated flame dynamics more delicate and realistic. In summary, through this flame lamp control circuit, two light-emitting units with opposite polarities within the same light-emitting group 100 can be alternately lit, and by using fewer electrical connection lines S than the number of light-emitting units to control multiple light-emitting units, these units can be lit and extinguished sequentially, resulting in a more delicate and realistic simulated flame effect.

[0050] In other embodiments, depending on the requirements, one or more groups of light-emitting groups 100 can be turned on or off for a long time, while other light-emitting groups 100 are turned on or off in a specified order to simulate different flame effects.

[0051] In some embodiments, the relationship between the number of M electrical connection lines S and the number of N light-emitting units satisfies the following equation:

[0052] N = M × (M-1)

[0053] Specifically, N represents the total number of light-emitting units, and M represents the number of electrical connection lines S. Since each electrical connection line S can cooperate with the remaining (M-1) electrical connection lines S to form a light-emitting group 100, and each light-emitting group 100 contains two light-emitting units, the total number of light-emitting units N is equal to the product of M and (M-1). Through this quantitative relationship, a larger number of light-emitting units can be independently or alternately illuminated while ensuring a limited number of electrical connection lines S, thus presenting a more delicate and realistic flame effect under the same hardware conditions. Figure 2 As shown, when there are 5 electrical connection lines S, the control module 40 can control 20 light-emitting units.

[0054] In some embodiments, the control module 40 controls the level state of different electrical connection lines S, which can cause multiple light-emitting groups 100 to light up sequentially from the first group to the Pth group, or sequentially from the Pth group to the first group. The Pth group is the last group of multiple light-emitting groups 100 arranged in a predetermined order. By lighting up multiple light-emitting groups 100 in the order of arrangement, the control module 40 enables multiple light-emitting units to form a dynamic effect similar to flame jumping. The reverse lighting order can enable the flame lamp using this control circuit to have multiple display forms, which can expand its application scenarios.

[0055] Reference Figure 2 In some embodiments, the control module 40 includes a microcontroller unit. Multiple I / O pins of the microcontroller unit are electrically connected to multiple electrical connection lines S, used to control the voltage levels of the electrical connection lines S. For example, the microcontroller unit has eight I / O pins, of which two are used for external power supply, one is used to connect to a switch K, and the remaining five are used to connect to five electrical connection lines S. In this case, the number of light-emitting units connected to the five electrical connection lines S is 20. Thus, by occupying only five I / O pins, the lighting control of 20 light-emitting units can be achieved. Compared to the traditional method where one I / O pin can only control the lighting of one light-emitting unit, this control circuit can achieve lighting control of a much larger number of light-emitting units than the number of electrical connection lines S, thereby significantly reducing the occupation of the microcontroller unit's I / O pins. Figure 2 As shown, the five electrical connection lines S specifically include electrical connection lines S1, S2, S3, and S5. At this time, there can be 20 light-emitting units. For a light-emitting group of 100, there are 10 groups. The 20 light-emitting units specifically include light-emitting unit U1, U2, U3, U4...U17, U18, U19, and U20. When the 20 light-emitting units are arranged according to... Figure 2 The arrangement shown forms light-emitting unit U1 → light-emitting unit U20, and the polarity direction of each light-emitting unit (light-emitting diode) is as follows: Figure 2 As shown, the control module 40 applies level changes to the line pairs (S1,S2), (S2,S3), (S1,S3), (S4,S3), (S5,S3), (S4,S2), (S5,S2), (S4,S1), (S5,S1), and (S5,S3) in sequence, and switches the polarity relationship within each short time window. This enables the sequential lighting of U1→U2→U3→U4→U5→U6···U15→U16→U17→U18→U19→U20, creating a dynamic effect similar to a flickering flame.

[0056] Since the flame lamp can be installed facing upwards or downwards, a switch can be installed to ensure that the flame dynamically appears upwards regardless of whether the lamp is placed upwards or downwards. This switch controls the lighting sequence of multiple light-emitting units, allowing them to light up in either the order U1→U2 or U20→U1. (Refer to...) Figure 2 The control module 40 includes a switch K, which can change the lighting order of multiple light-emitting groups 100. Specifically, the switch K is located on an IO pin of the microcontroller unit. Users can manually control the switch K to change the lighting order of multiple light-emitting units so that when the flame lamp is installed facing up or down, the simulated flame is dynamically displayed facing up.

[0057] In some embodiments, the control module 40 further includes a gravity sensor for detecting the placement direction of the flame lamp and changing the lighting sequence of multiple light-emitting groups 100 based on the detection result. Based on the placement direction of the flame lamp detected by the gravity sensor, the lighting sequence of multiple light-emitting groups 100 (i.e., multiple light-emitting units) is automatically changed. To further reduce the IO pin occupation of the microcontroller unit, the control module 40 includes a switch and a gravity sensor. The gravity sensor is linked to the switch, and the gravity sensor is used to change the connection circuit of the switch when the flame lamp is placed upright or upside down, thereby changing the lighting sequence of the multiple light-emitting groups 100; Figure 2 As shown, gravity sensor C is located inside switch K. When the flame lamp is placed facing forward, gravity sensor C is connected to terminal a inside switch K, allowing multiple light-emitting units to light up in the order of U1→U2. When the flame lamp is placed facing backward, gravity sensor C is connected to terminal b inside switch K, allowing multiple light-emitting units to light up in the order of U20→U1. The linkage between the gravity sensor and the switch allows the flame lamp to automatically change the lighting order of multiple light-emitting units regardless of whether it is placed facing forward or backward, so that the flame simulated by multiple light-emitting units appears upward. Furthermore, the gravity sensor and the switch share a single IO pin, reducing the IO pin occupation of the microcontroller unit and allowing the microcontroller unit to have more free IO pins for connecting electrical connection lines S, thereby expanding the number of controllable light-emitting units.

[0058] Embodiment 2 of this utility model also proposes a flame lamp.

[0059] Reference Figures 3-5 The flame lamp includes the flame lamp control circuit described in Embodiment 1. The flame lamp also includes a strip substrate 50, which has a length direction and a width direction. Multiple light-emitting units are continuously arranged along the length direction of the strip substrate 50 and staggered from each other in the width direction of the strip substrate 50. The multiple light-emitting units form a light-emitting path 10. The control module 40 is used to control the multiple light-emitting units to light up or turn off.

[0060] Specifically, the strip-shaped substrate 50 has a slender structure with a clearly defined length and width direction, the length direction being... Figure 4 The Y-axis direction shown is the width direction. Figure 4 The X-axis direction is shown; the light-emitting unit includes at least one LED bead 101, as illustrated by the description of the light-emitting unit including one LED bead 101. Figure 4 As shown, multiple light-emitting units (LED beads 101) are continuously arranged along the length of the strip substrate 50 and staggered in the width direction. That is, the arrangement path of the multiple light-emitting units (LED beads 101) on the strip substrate 50 is the light-emitting path 10 formed by the multiple light-emitting units (LED beads 101), and the light-emitting path 10 is continuous in the length direction of the strip substrate 50 but staggered in the width direction, forming a tortuous light-emitting path 10. The control module 40 uses a control circuit as described in Embodiment 1 to electrically connect with the multiple light-emitting units, and is used to control the light-emitting units to light up sequentially according to a preset timing sequence, thereby simulating the dynamic effect of a flame. Unlike the linearly arranged light-emitting units in the prior art, this embodiment introduces a staggered arrangement in the width direction, so that the light-emitting path 10 of the flame lamp is no longer limited to a single vertical straight line, but forms a left-right swinging trajectory. Under the timing control of the control module 40, the lighting sequence not only reflects the up-and-down jumping of a traditional flame, but also further superimposes the visual effect of left-right swinging, thus making the flame simulation more delicate and realistic.

[0061] In other embodiments, the control module 40 can control one or more light-emitting units to be lit or turned off for a long time, while the remaining light-emitting units continue to be lit according to the settings to achieve a light rhythm effect, so that the flame lamp can simulate flames with different effects.

[0062] In some embodiments, the strip substrate 50 is rigid and is arranged in a tortuous shape along its length, so that the arrangement path of the multiple light-emitting units is tortuous. Specifically, the strip substrate 50 is a rigid circuit board, cut and shaped in a tortuous shape along its length, so that the arrangement path of the multiple light-emitting units disposed on the strip substrate 50 is itself tortuous, that is, the tortuous shape of the strip substrate 50 directly determines the tortuous shape of the light-emitting path 10. By directly realizing the tortuosity in the substrate shape, not only is the stability of the light-emitting path 10 guaranteed, but it also facilitates the rapid realization of the overall layout during mass production. In other embodiments, the strip substrate 50 may also be a flexible circuit board, which is cut and shaped according to a specified shape to realize light-emitting paths 10 with different tortuous shapes.

[0063] Reference Figure 4In some embodiments, the strip substrate 50 has an S-shaped bend, causing the arrangement path of the multiple light-emitting units to be S-shaped, i.e., the light-emitting path 10 is S-shaped. Specifically, the strip substrate 50 adopts an S-shaped bend, causing the multiple light-emitting units to be gradually staggered along the length direction, such as... Figure 4 As shown, the LED beads 101 distributed in the upper half of the S-shaped strip substrate 50 are generally biased to one side, and the LED beads 101 in the lower half are generally biased to the other side, forming an "S"-shaped light-emitting path 10. The light-emitting path 10 roughly covers the S-shaped strip substrate 50, so that the light from the light-emitting path 10 can cover the strip substrate 50. When lit, the dynamic effect of the flame is characterized by both up-and-down fluctuations and left-and-right swaying. The S-shape is a smooth transition curve, making the simulated flame effect more stable.

[0064] In other embodiments, even if the strip substrate 50 is a straight strip structure, multiple LED beads 101 can still form a tortuous arrangement path on it by staggered arrangement. For example, by distributing LED beads 101 sequentially on the left and right sides of the straight plate, the overall light-emitting path 10 can present an "S-shape", "Z-shape" or "Y-shape".

[0065] Reference Figure 5 The flame lamp also includes a base 70, a lampshade 80, and a mounting plate 90. The mounting plate 90 is integrally formed with the strip substrate 50. The control module 40 is disposed on the mounting plate 90, and the mounting plate 90 is used to fix it to the base 70. The lampshade 80 covers the base 70 and surrounds the strip substrate 50. The light from the multiple light-emitting units on the strip substrate 50 can be emitted through the lampshade 80.

[0066] In summary, the flame lamp of this embodiment, through the staggered arrangement of the strip substrate 50 and its multiple light-emitting units in the width direction, combined with the point-to-point lighting sequence of the control module 40, makes the light-emitting path 10 present a tortuous shape such as S-shape, Z-shape, or Y-shape. Based on the traditional up-and-down jumping flame effect, a dynamic effect of left-and-right swaying is added, significantly improving the realism and visual appeal of the flame simulation, and meeting the market demand for flame lamps with higher simulation fidelity.

[0067] Embodiment 3 of this utility model also provides a flame lamp.

[0068] The structure of the flame lamp in Embodiment 3 is roughly the same as that in Embodiment 2, except that the twisted shape of the strip substrate 50 is different.

[0069] Reference Figure 6The Z-shaped shape of the strip substrate 50 causes the arrangement path of multiple light-emitting units to be Z-shaped. Using the Z-shaped strip substrate 50 makes the overall light-emitting path 10 appear as a Z-shaped arrangement. When the control module 40 drives multiple light-emitting units to light up from one end of the strip substrate 50 to the other, the light-emitting path 10 jumps up and down while alternately swinging left and right, simulating a brighter flame effect. It should also be noted that the Z-shaped strip substrate 50 can also be mounted on the base 70 at an angle, making the strip substrate 50 visually appear as a lightning bolt shape.

[0070] Embodiment four of this utility model also provides a flame lamp.

[0071] The structure of the flame lamp in Embodiment 4 is roughly the same as that in Embodiment 2, except that the twisted shape of the strip substrate 50 is different.

[0072] Reference Figure 7 The strip substrate 50 has a Y-shaped bend, which makes the arrangement path of multiple light-emitting units Y-shaped. At this time, the light-emitting units are relatively concentrated at the lower end of the strip substrate 50, while they are dispersed to the left and right sides at the upper end, forming a forked light-emitting path 10. When the control module 40 is lit in a bottom-up sequence, the light-emitting effect is that the flame converges from the bottom and then disperses to the left and right, presenting a special forked flame effect.

[0073] Embodiment 5 of this utility model also provides a flame lamp.

[0074] The structure of the flame lamp in Embodiment 5 is roughly the same as that in Embodiment 2, except that the twisted shape of the strip substrate 50 is different.

[0075] Reference Figure 8 Multiple strip-shaped substrates 50 are provided, and the multiple strip-shaped substrates 50 are connected end to end along their length direction, such as... Figure 8 As shown, when the strip substrate 50 is arranged in an S-shaped zigzag form, multiple strip substrates 50 are connected end to end along their length to form a curved substrate, thereby forming a curved light-emitting path 10. The multiple strip substrates 50 can also be manufactured using a one-piece molding process, for example, by selecting a longer circuit board and cutting it into a curved shape formed by multiple S-shapes. In other embodiments, multiple Y-shaped or Z-shaped strip substrates 50 can also be connected end to end.
